You're dealing with what I think is the ultimate challenge for those of us who grow lots of Hoyas in close proximity. I have to detangle mine almost daily this time of year. But sometimes I don't get to them early enough and end up with a situation I have to live with, like fungii which grows like a weed and puts on vines along my shelves and leaves grow through small spots so that I either have to leave them or pop leaves off to move them... But I'm just always happy they're growing well enough for me to have such problems...
